What is it you’re trying to do. If you’ve set your system up with your Fire HD, whatever that is, and can use it in that way, what further set-up is required for Android? If the system is all set up, you simply log in to the app, with the same account details, on any device, and everything will automagically be there.

Once it is set up the Sync unit only controls/monitors cameras via UHF radio and communicates to Blinks servers over your WiFi.

The Blink Apps are getting their information via the cloud not via the local sync unit (Which is why it still works 100’s of miles away) If the App is not working on your android device you may find help for that in the FAQ
